“…However, the minimum response-time of the charge sensitive preamplifier is normally 10~20 ns, therefore it is difficult to measure charge-carrier transit times shorter than 10 ns [8,9]. Moritz et al [10] have developed a broadband preamplifier aimed mainly at high counting rate capability, but there was no description on output linearity.…”

There are continuing efforts of developing faster FETs and diamond is one of the strong candidates as a base semiconductor. Since the upper-limit-frequency of diamond FETs determines saturated drift-velocities of charge-carriers, we need to first characterize diamond to develop better FETs. It is, however, not easy to measure the velocities with response time of less than 20 ns. Therefore, we developed a drift velocity measurement system using a time-of-flight (TOF) technique with a UV laser with 100 ps pulse-width. In order to realize response times faster than 20 ns, we employed a 50 ohm coaxial cable as a load, with which we could effectively reduce the stray capacitance and inductance, and also, suppress reflections in the signal which gives false signals. As a result, we can measure carrier-transit times shorter than 10 ns.

“…The detector has four squared metalized faces Q 1−4 (10x10) mm 2 each. Each of them was connected to a broadband DBA amplifier [8]. The time resolution and the charge collection efficiency of the pcCVD-DD have been monitored via digital scope during low intensity runs taking place at the end of each series.…”

We report on characterization of several single crystals CVD diamond detectors tested for the use in heavy-ion spectrometry and minimum ionizing particles time of flight measurements. An energy resolution of 16 keV (FWHM) is achieved using a 241 Am α-source, which is comparable to the energy resolution of silicon detectors. The collected charge maps, measured using 12 C micro beams confirm the excellent homogeneity of the novel material. Using low impedance broadband electronics and a transient-current technique the mobility and saturation drift velocity of electrons and holes are estimated.
